Abstract

Background: During liposuction procedures, injection of wetting solution containing epinephrine is performed. This may increase the risk of cardiovascular side effects in large volume cases. Magnesium sulfate has cardioprotective effects, and can prevent complications related to epinephrine.
The aim of the work: To assess the effect of adding intravenous magnesium sulfate, during the administration of epinephrine containing wetting solution, on the incidence of epinephrine-mediated cardiovascular side effects during liposuction surgery.
Patients and Methods: This was a prospective randomized study comprised a total of 94 cases into two equal groups. The epinephrine group included 47 cases that had epinephrine in their wetting solution, and epinephrine-Mg group included the remaining cases that had adrenaline in the wetting solution along with intra venous. administration of MgSO4. Heart rate, blood pressure, arrhythmia incidence, isoflurane, and morphine consumption were recorded. 
Results: No significant difference was noticed as regard basal and induction heart rate and mean arterial pressure [MAP]. However, the epinephrine-Mg group showed significantly lower readings on subsequent assessment. There was no significant difference among both groups regarding the incidence of arrhythmia; the epinephrine group had more cases with arrhythmia. Isoflurane consumption decreased significantly in the epinephrine-Mg group in comparison with the epinephrine group, while morphine consumption did not significantly differ between them.
Conclusion: Based on our findings, intravenous administration of magnesium sulfate decreases heart rate, blood pressure, and inhalational anesthesia consumption during liposuction. However, it has no significant impact neither on the incidence of arrhythmia, nor morphine consumption.
